I think every programming enthusiast should try it. Especially with something like a microcontroller where you really need to care about the stack/heap and living inside of a few 100k of ram.

Now it has extremely high level libraries on the DEFAULT spec so you can do things that any extremely high level language like python did by default (like text parsing) and I think if it had those features from the start dozens of popular languages would not even EXIST.

  • "using namespace std;" is kind of an anti-pattern. It's almost like saying "import *" in Python. You code becomes more terse, but now you can't tell if a keyword is builtin or from the namespace (or from the other namespace you 'used'/imported). And never put this in a header file, it'll hose anyone who includes your header.

    • He is "keeping it usual" by calling it the shift left operator. Given that it is overloadable, its meaning in any particular context could be anything, but its usual meaning is shift left, which is therefore the best name for the operator overall.

    • But it _is_ the bitwise left shift operator. You might not call it that, but many C++ programmers do. Bitwise operations are the original purpose of the shift operators. The only reason they're called stream operators after the fact is because the developers of std::iostream overloaded them for covenience.

The result was what I can only describe as a mild form of PTSD, where I would cry every time I talked about how I didn't understand programming. This lasted for multiple years; only recently has that trauma worn off enough to where I can have an interest in programming again. And yes, typing that semicolon in the previous sentence was still painful.

    • @@someshwartripathi8446 My perspective can be different, but it's somehow related to the people who criticize C++ :) As, I have seen many people (mostly unguided beginners, unfortunately) who start working in C++, and then get frustrated by the warnings and errors, which the compilers give (many times causing a cascade of errors). Instead, they start working in some higher level language, and the code just “runs”. They become happy, but when the code is used in real-time scenarios, they get badly failed. And it gets extremely difficult, and complicated to trace down that error, they made in their logic. Simply, we should always try to improve ourselves, optimize our logics, and only then compiler will help us grow along. Otherwise, you may have got the meaning of blowing the foot off :)

  • A couple things to add: 1. C code is likely to not run on C++ compilers because of the fact that C++ doesn't consider some C keywords as valid (like restrict) 2. It's advised to avoid using namespace std and instead either use something like using std::cout or just using std::cout all the time.

  • 2:30 std::unique_ptr ptrJeff(new Human); When using the new keyword, allocate is still done to the heap like a normal pointer. Consider this instead: std::unique_ptr ptrJeff = std::make_unique(); Or, even: auto ptrJeff = std::make_unique(); This is especially important for shared pointers. For unique pointers, the only difference in the end is exception handling. Also, smart pointers need #include . Another thing to keep in mind is that these were added in c++11, so it might even be a good idea to specify. -std=c++11 or later.

    @astralchan@astralchan2 жыл бұрын
    • make_unique also allocates on the heap. There's no difference there. The main difference between using make_unique and unique_ptr(new x) is with exceptions: if you have an expression with two unique_ptr(new bla) subexpressions, the order of evaluation is unspecified which means you might run two "new"s and then the two unique_ptr constructions. If the second new throws an exception, the first one will leak. This may have been fixed with the evaluation order changes in c++17 but I don't see a point in risking it. make_unique also has a teachability benefit in that you can give a blanket guidelines like "never use the keyword new" and it'll be valid every time.

    • There are performance reasons as well. make_unique and make_shared construct the object in place, rather than creating a temporary object and then having to move or copy it. The arguments to make_shared are the same as the constructor for that class. This also applies to emplace_back and emplace_front in various containers, as opposed to push_back or push_front which will have to move/copy the object. smart pointers will still delete the memory if you assign a raw pointer to them, as they own that pointer now. But as Votlu points out, there might be a leak if there's an exception between your "new" and the return of make_unique. You also have to be sure you're not using that raw pointer any more after you give ownership to the smart pointer.

      @DFPercush@DFPercush2 жыл бұрын
